Competition in a rough neighborhood: Plant success in a desert environmentMany people think of deserts as inhospitable places devoid of life, but numerous plants and animals have adapted to this harsh environment, where they often compete for limited resources. In desert environments, the most limited resource is usually water, forcing plants to adopt different strategies to compete with their neighbors for this precious resource.http://phys.org/news307712471.html

BiologyWed, 25 Sep 2013 07:50:01 ESTnews299310823Using gold and light to study molecules in waterThanks to a new device that is the size of a human hair, it is now possible to detect molecules in a liquid solution and observe their interactions. This is of major interest for the scientific community, as there is currently no reliable way of examining both the behavior and the chemical structure of molecules in a liquid in real time.http://phys.org/news294491219.html
